CARRIAGE-CURTAIN FASTENER.

sPEcIrIcATIoN forming part of Letters Patent No. 289,991, dated December11, 1883.

Application filed October 1, 1883. (No model.)

To all whom/it may concern:

'Be it knownthat I, WILLIAM E.'OURTIs, of Oincinnatipflamilton county,Ohio, "have Invented a new and useful'Improvement in Carriage-CurtainFasteners, of which the following is a specification.

My invention has for its object a simple, compact, and durable fasteningor button for carnage-curtains, whose construction "is such as to enableit to retain the locked (and preferably also'the unlocked) condition, ashere- .inafter more particularly set forth. I

My invention consists in the. construction hereinafter described, andpointed'out in the claim. I

In the accompanying drawings, Figure 1 is a partly-sectioned elevationof a carriage-curtain fastening embodying my invention. Figs. 2 to 11,inclusive, represent modifications of the same. Figs. 12, 13, and 14 areenlarged sections, to represent diverse forms of lockinglip. Figs. 15and 16 represent such a fastening in its disengaged and lockedconditions,

respectively.

A representsth'e seat or support, to be rigidly, secured to the frame towhich the curtain is to be fastened, and B the fixed pivotof button 0.In my preferred form (shown in Figs. 1 and 2) the said pivot is a pieceof wire, which extending through said seat, its

rear portion, B, becomesthe means of securing theseat. to the carriagebow or post,.and may for that purpose be either screw-threaded, as inFig.1, for screwing into the substance of the bow or post, or bethreadless, as in Fig. 2,

in order that, being passed through the post,

it may be riveted on the other side thereof. This bolt B B may besecured in the seat A either by screwing 1 through the same or bycastingthe seat about such a bolt in a suitable mold. Both seat andbutton are of the represented aoval orbtheroblong form. (See Figs. 4;,15, and 16.) Thebutton O hasprojecting from its sole a longitudinaltongue, 0, which,in the locked position of the button, occupies agroove, a,that is-coincident with the short diameter of the seat A. Arecess, .0, in the buttonreceives a helical spring, D, which, beingconfinedby nut E, (or by a washer, E, outside of which the bolt B isriveted,) holds the button with sufficient stress to its lockedcondition to prevent accidental displacement therefrom, (see Fig. 16,)but permits the easy turning of the button to the unlocked condition.(See Fig. 15.)

In addition to the groove a, which is coincident with the seats shortdiameter, there may be a similar groove, a, coincident with its longdiameter, so as to hold the button with equal accuracy to the unlockedthat it does to the locked condition.

' In fasteners to be attached to wooden bows orposts, spurs F areprovided on the rear of the seat, to enter the substance of the post.

G and H represent, respectively, portions of a post and curtain of avehicle-canopy, and I a customary eyelet.

. The above-described preferred form of my invention may be modified innon-essential particulars. For example, the button may have tworectangularly-intersecting tongues, or the tongue or tongues may be onthe seat, the grooves being on the button. (See Fig. 11.) A suitablehole being provided in the seat, the pivot-bolt BB may be the means forfastening both seat and button, as shown in Figs. 3 and 5,a head, 6,upon the said bolt serving to hold in the spring, thus dispensing with aseparate nut or washer. The seat may be secured to the post by one ormore shanks or by distinct bolts, the pivot-bolt being a separatemember, as in Figs. 4., 7, 8, and 10. The tongues may be ofdiverseshapes in transverse section. (See. for example, Figs. 12, 13,14.) A block of rubber may be employed instead of the helical spring.

I claim as new and of .lmy' invention In a carriage-curtain fastening,the. combination of base A, provided with means for securing it rigidlyto the frame, a cross-groove, a, and a stationary pivot,'iB, a recessedbutton, 0, to turn on the pivot, having a tongue, 0, to engagethegroove, and aspring located in the recess around the pivot between thehead of the pivot and the inner end of the recess, to press thebuttonto'the base, as set forth.

In testimony of which invention I hereunto set my hand. 1
